Call and data correspondence in a call-in center employing virtual restructuring for computer telephony integrated functionality

An Internet Protocol Network Telephony (IPNT) call-routing system, comprising:

• an Internet Protocol call-in center comprising a plurality of agent stations, individual ones of the agent stations having a computer platform including a video display unit (VDU), a telephone and a computer platform connected by a Telephone Application Programming Interface (TAPI)-compliant bridge, with a plurality of the computer workstations connected to one another, to a first processor, and to a database on a local area network (LAN);
• and
• a network-level IPNT call-routing center comprising a processor adapted to route IPNT telephone calls to the computer platforms at the agent stations;
• wherein the computer workstation retrieves origination data for incoming calls, reports the origination data to the first processor, wherein the first processor uses the origination data to correlate a caller with further data retrieved from the database for display on the VDU, and wherein the first computer processor services calls from specific Service Control Points (SCPs) and blocks display of data at agent station VDUs for any call not identified as originating at one of the specific SCPs.
